The sound is even I think a little too loud. But maybe that’s what it takes.

The goods arrived on time

In general, I liked the relay, considering that the price with the coins came out a little more than three bucks. High quality workmanship: Nice brand packaging, quality housing with DIN rail mount, neat soldering. With the application Tuya finished without problems. But with control over the radio channel, 433 MHz is not very good. First, the remote pairing mode can only be entered through the app. The binding process itself is complex, buggy and intuitive. Second, it looks like control goes through the Tuya server. A very long reaction, sometimes teams do not reach or duplicate. I will try to flash it on openbeken.

Everything connected instantly smart life works so far without errors. The package arrived quickly
